"The .present invention `relates :to doors, `particularly applicable to farm-.buildings for housing livestock `andan object of the .present invention is to providea door which is light, strong, `semi reproof and easily-.manufactured `at loW .cost.

(Dne-of the objectsfof .the present invention is `to provide a door .Whichgis designedzto retard heat `transfer :from I.the exteriorto the interioror vice Iversa.

vA `further object ofthe present invention is to vprovide 1a door `which has :a pleasing appearance yand can `be madeto harmonize with Kthe exterior` of va building having outside .metal sheathings.

"To [these Vand .other yuseful ends my invention consists fof .parts .and fcombinations .of parts, or itheir equivalents, Aas hereinafter `described .and claimed and `shown in the .accompanying ydraw- `ingsin which:

Fig. 10 is an enlarged fractional sectional view as shown in Figure 2.

Fig. 11 is a sectional view of a modification.

As thus illustrated, the preferred form of my invention is illustrated in Figures 1 to 5 inclusive and Figures 7, 8 and 10 and comprises side door frame members Ill-II) and upper and lower frame members 9-9. Members 9 and I0 are preferably made from wood pieces which are joined together at their ends as illustrated in Figures 7 and 8.

I provide a panel I2 which is adapted to ll the space within the frame and occupy grooves on the inner surface of the frame members as clearly illustrated in Figures 3 and 10 and is preferably made of insulatingboard or the like. I provide metal sheathings` II--II which are (Cl. ,Z0-3.5)

adapted to surround frame members `9 and sheathings I'3--4I3 which are adapted to surround `members Ill as clearly indicated in Figures 1,2, 3 and 10. The inner edges of members IiI .and

I3 are -bent .over the `inner Ledges of members 9 `and II) -and then inwardly a short distanceas `at rIII so as toembrace panel I2 (see Figure 10.)

`I Aprovide panel Vsheathing members Awhich ll `the space lwithin the frame, the edges being preferably folded as at `It terminating adit `jacent the inner edge of member 1I4. The edges of sheathing members `I5 .rest preferablyon the outer Lsurface of members III land are secured to `the assembly preferably` by means of spaced `rivets |11, `these rivets lpassing through the as- 'i sembly as illustrated to thereby form a strong and rigid :joint -between `the frameand panel.

It :will be noted that members l5 are separated .from panel iii-2 by a 4Panel `sheathings :I 5 a `dead air space as -at I8.

reicorrugated preferably as I,

l'illustrated 1in fFigure 2 wherein the corrugations illustrated and preferably spaced Vin groups of two near the Aedges of the panel and four in each of the other groups, the

ygroups being `spaced preferably as illustrated in Figures 1 and 2.

Thus it will be seen that a considerable dead air gap is provided be and the panel thereby to add to the insulating` tween the panel sheathngs properties of the door.

It will be noted by referring to Figures 1 and 4 that sheathings I3 embrace the ends of sheathings II. illustrated in Figures thickness of sheathin to make a smooth fr offset as at (see Figure 4).

also offset as at 2I.

That is, at the frame joints which are 7 and 8 there is a double gs on each side. In order ame face, members II are Members II are In order to accomplish the sheathings, that the short distance by the panel is embraced for a frame sheathings and that this assembly is embraced on opposite sides by the edges of the panel sheathings and secured together by means of spaced rivets or bolts forming a very rigid structure.

As thus constructed, the side frame members of the door provide a suitable surface upon which the hinges and latches may be secured by means of bolts or otherwise.

In Figure 1 I have illustrated three half hinges 22 and a latch mechanism 23 as being secured to the frame by means of bolts 24, which, it will be noted, (see Figure 2) extend entirely through the frame structure thus the door is not only simple, strong and neat in appearance, but also provides a suitable background upon which to fasten the hinges and latches.

In Figures 6 and 9 I illustrate a modification wherein the panel 36 is made the full size of the door and the frame is formed by means of strips 31 and 38 which are secured to the panel as illustrated. Strips 38 form the side frame members and strips 31 form the top and bottom frame members. In this design, side frame member sheathings 30 terminate as at 3l. The remainder of the inner edges of members 30 are bent down so as to form flanges which are similar to anges I4 in the other ngures. This sheathing design may also be used on the frame members as illustrated in the other gures, the advantage being that the sheathing 30 extends a short distance over the joint formed by the splice in the frame members.

In Figure 10 I illustrate in enlarged form the preferred structure as shown in Figures 2 and 3. In Figure 11 I illustrate a structure which is similar to that shown in Figures 1, 2 and 3 except that the panel 40 is not mortised into the frame members. In this design the side frame members are designated by reference numeral 39 and the panel is designated by numeral 40 the side frame member sheathing by numeral 42 having a .bend as at 43 and inwardly extending flanges 44. Panel sheathings 45 are identical to the sheathings illustrated in the other gures except that their edges are placed under flanges 44 and the entire structure held together by means of rivets 48, the dead air space 49 being somewhat less than dead air space I8, air space 49 being formed by the folded ends 41 ofthe sheathing panel, This space is such as will cause the apex of the corrugations to contact the panel as at 50.

Clearly many minor details changes may be made without departing from the spirit and scope of my invention as recited in the appended claims.

Having thus shown and described my invention, I claim:

1. A door of the class described, comprising a frame formed from four rectangular in cross section strips of wood, the ends being lapped forming a rectangular frame, a panel having considerably less thickness than the thickness of the frame and adapted to close the opening therein, four U-shaped metal sheathings each adapted to embrace the outer edge and sides of a frame member for the full length or width of said frame, the sides' of adjacent ends of said U-shaped sheathings being lapped one over the other, anumber of bolts or rivets adapted to bind the lapped parts of said sheathings and frame together, the inner edges of said frame sheathings being folded around the inner corners of the frame members and then being bent inwardly forming relatively narrow flanges which lie on opposite sides of said panel, panel sheathings positioned on opposite sides of the panel their edges lying on said anges, said flanges, panel sheathings and panel being secured together by spaced bolts or rivets.

2. A door of the class described, comprising a rectangular frame having a panel therein of considerably less thickness than the thickness of the frame, four U-shaped metalv sheathings each adapted to embrace on outer edge and sides of a frame member for its full length or width, the sides of adjacent ends of said U-shaped sheathings being lapped one over the other, a number of bolts or rivets adapted to bind the lapped parts of said sheathings and frame together, the inner edges of said frame sheathings being folded around the inner corners of the frame members and then being bent inwardly forming relatively narrow flanges, panel sheathings positioned on opposite sides of the panel their edges lying against said anges, said flanges, panel sheathings and panel being secured together by spaced bolts or rivets.
